How to Make Dad’s Creamy & Cheesy Au Gratin Potatoes
Step 1: Preheat Your Oven
Start by preheating your oven to 375 degrees F. This ensures that your au gratin potatoes will bake evenly and come out perfectly golden brown.
Step 2: Prepare Your Baking Dish
Spray a 2-quart square baking dish (or an 8×12 dish) with nonstick cooking spray or grease it with butter or oil. This step is essential so that nothing sticks during baking!
Step 3: Layer the Potatoes and Onions
Place sliced potatoes in three tight slanted rows in your prepared dish. Leave just enough space between slices so they can cook properly without becoming mushy. Nestle onion slices among the potatoes wherever you can fit them—this adds sweetness as they roast.
Step 4: Make Your Sauce
In a saucepan over medium heat, melt your butter. Once melted, whisk in a bit of flour before slowly adding almond milk, alternating with more flour while whisking vigorously to prevent lumps. You want this mixture to simmer until it reaches a creamy gravy-like consistency.
Step 5: Add Cheese and Seasonings
Turn down the heat to low and stir in your shredded cheddar cheese along with garlic powder, salt, and pepper. Taste your sauce—this is where you can adjust seasoning to match your liking!
Step 6: Pour Over Potatoes
Pour your creamy sauce evenly over the arranged potatoes and onions. Don’t worry if it looks like there’s too much sauce—it will soak into everything as it bakes!
Step 7: Bake Covered
Cover your baking dish with foil and bake in the preheated oven for about 45 minutes. This helps steam the potatoes while allowing them to absorb all that cheesy goodness.
Step 8: Add Toppings and Finish Baking
After removing the foil, sprinkle your gruyere cheese (or additional cheddar) along with parmesan on top of those beautifully baked potatoes. Return them to bake uncovered for another 30-45 minutes until bubbly and golden brown.
Step 9: Garnish and Serve
Once done, take them out of the oven and garnish with fresh chopped parsley for that lovely finishing touch. Enjoy every creamy bite!
I hope you love making Dad’s Creamy & Cheesy Au Gratin Potatoes as much as I do! Happy cooking!
Pro Tips for Making Dad’s Creamy & Cheesy Au Gratin Potatoes
Making the perfect au gratin potatoes is all about technique and attention to detail. Here are some helpful tips to ensure your dish turns out creamy, cheesy, and utterly delicious!
-
Use uniform potato slices: Cutting your potatoes into even 1/8th inch rounds ensures that they cook evenly. This way, every bite is perfectly tender and creamy.
-
Don’t skip the simmering step: Allowing your sauce to come to a gentle simmer before adding cheese helps the flavors meld beautifully and prevents clumping. A smooth sauce will coat your potatoes perfectly.
-
Taste as you go: Seasoning is key! Make sure to taste the sauce before pouring it over the potatoes. Adjusting salt and pepper during cooking allows you to achieve the perfect flavor balance.
-
Cover while baking initially: Covering the dish with foil during the first part of baking traps steam, which helps cook the potatoes through without burning the top. Just don’t forget to remove it later for that golden crust!
-
Let it rest before serving: Allowing your au gratin potatoes to sit for about 10-15 minutes after baking helps them set up a bit more, making it easier to serve those beautiful layers later on.

- Crushed red pepper flakes: For those who enjoy a little heat, a dash of red pepper flakes on top provides a nice kick and visual appeal.
Side Dishes
- Roasted vegetables: Carrots, Brussels sprouts, or zucchini tossed in olive oil and roasted until caramelized pair wonderfully with creamy potatoes for a balanced meal.
- Grilled chicken or fish: A light protein option like grilled chicken breast or salmon makes for an excellent complement, allowing the richness of the au gratin to shine without overwhelming the palate.
- Simple green salad: A crisp salad with mixed greens, cherry tomatoes, and a light vinaigrette adds freshness and crunch, balancing out the creaminess of the potatoes.
